Yes, I have. It was a workshop and we ended up with 20FQs in various colors. It was fun but I probably won't do it again. There are too many on-line sites to buy gorgeous hand-dyed fabrics and even though they may be pricey you have to balance that against the drawbacks of doing your own. IMHO the start up costs, the mess, the environmental concerns over disposal of left over dye solutions, the problems of not being able to accurately repeat a perfect shade of something, etc. Nope, I'm perfectly content buying the gazillion fabrics that companies already put out. Just MY opinion.
